ANSWER:
The second step in the process for factorising the trinomial x^2 - 4x - 32 is either:
x^2 - 8x + 4x - 32
OR
x ( x - 8 ) + 4 ( x - 8 )
This is as some people may skip the second step that I have shown whilst some people may complete the additional step.
STEP-BY-STEP EXPLANATION:
= x^2 - 4x - 32
= x^2 - 8x + 4x - 32
= x ( x - 8 ) + 4 ( x - 8 )
= ( x - 8 ) ( x + 4 )
